Ivanka Trump joined those criticizing the decision, calling on the Women's Tennis Association to change its rules concerning maternity leave.

The Women's Tennis Association has been generating controversy following news that Serena Williams will be unseeded at the French Open following her maternity leave — and now Ivanka Trump has stepped in to criticize it.

"I think it's more of a protection for women to have a life," Williams told The Times. "You shouldn't have to wait to have a baby until you retire. If you want to have a baby and take a few months off or a year off and then come back, you shouldn't have to be penalized for that. Pregnancy is not an injury."
